Answer:

if x is the number of miles driven, the equation is 2.25x + 12=30. solved: x = 8 miles

Step-by-step explanation:

First, you make the equation. If x is the number of miles, the price per mile would be 2.25 times x or 2.25x. You also have to add the one time fee of $12, so you have 2.25x + 12. Next, you're trying to find x if it costs $30 total so you would have 2.25x + 12 = 30.

Solving,

2.25x + 12 = 30

subtract 12 from both sides

2.25x = 18

divide both sides by 2.25

x = 8 miles

Quadrilateral QRST is inscribed in circle W as shown below. The measure of ∠QRS is 12 degrees less than three times the measure
Tju [1.3M]

<u>Corrected Question</u>

Quadrilateral QRST is inscribed in circle W as shown below. The measure of ∠QRS is 12 degrees less than three times the measure of ∠QTS and

mRQT=mRST .

(a)Determine the measure of Angle QTS .

(b)What is the common measure of angles RQT and RST ?

Answer:

(a)48 degrees

(b)90 degrees

Step-by-step explanation:

Theorem: Opposite angles of a cyclic quadrilateral are supplementary.

(a)

Let the measure of ∠QTS=x

Therefore: m∠QRS=3x-12

∠QTS and ∠QRS are opposite angles of a cyclic quadrilateral. By the theorem above:

x+3x-12=180

4x=180+12

4x=192

x=48 degrees

The measure of angle QTS is 48 degrees.

(b)Since mRQT=mRST

mRQT and mRST are opposite angles of a cyclic quadrilateral

Therefore:

mRQT+mRST=180 degrees

2mRQT=180

mRQT=90 degrees

Therefore, the common measure of RQT and RST is 90 degrees.

Anne runs 6 laps on a track. She runs a total of 1 mile, or 5,280 feet. Write and solve an equation to find the distance, in fee
4vir4ik [10]
To find the distance per lap, divide the total feet, which is 5,280 by the number of laps which is 6. This means that 5280/6=880ft
Thus, Anne runs 880 feet per lap.

I need help on this question please.
Varvara68 [4.7K]

Answer:

The ladder needs to be 26 ft long.

Step-by-step explanation:

So pythag is a^{2}+b^{2}=c^{2}

We have the height and distance from the window, so we need to find c

10^{2}+24^{2}=c^{2}

100+576= 676

\sqrt{676} = 26
